ClutterTimeline is a base class for managing time based events such as animations.
Note: Every timeline shares the same ClutterTimeoutPool to decrease the possibility of starvating the main loop when using many timelines at the same time; this might cause problems if you are also using a library making heavy use of threads with no GLib main loop integration. In that case you might disable the common timeline pool by setting the CLUTTER_TIMELINE=no-pool environment variable prior to launching your application.
